Prevent weight gain
A study by a group of scientists at Uppsala University, Sweden, found that lack of sleep can increase your weight by slowing your metabolism down. The research suggests that a good night’s sleep can actually prevent weight gain.
The Slumberland Slumber Survey discovered that one in three of us rate our sleep ‘poor’ to ‘terrible’. A bad night’s sleep can leave you struggling all day, whereas a restful night of uninterrupted sleep can help you feel ready to take on the world.
Almost two thirds of us blame our irritability on lack of sleep, according to the Slumber Survey. Our Slumberland spokesman says: “It’s unsurprising that only 1% of those asked in the survey claim to feel fantastic when they wake up.”
Look more attractive
According to a study published in the British Medical Journal, a sound sleep can make you look healthier and more attractive. 23 people were photographed in the study, after a normal 8 hours of sleep and after a night of sleep deprivation. The images were shown to 65 people who rated each photograph on health, attractiveness and tiredness. The sleep deprived group scored lowest in all three categories.
Make better decisions
We’ve all been told at some point to ‘sleep on it’ – hoping that your decision will be easier in the morning. Scientists believe that your brain searches for a solution to your problem even while you are asleep. So even if you don’t wake with an answer, you’ll feel fresh and rested and able to make a better decision after a restful night of sleep.
It’s true. People who sleep less have a shorter lifespan. Studies have found that people who sleep fewer than six hours at night have a higher risk of dying sooner than people of a similar age who get their eight hours.
Be a winner
A good night’s sleep will improve athletic performance. As part of a study in 2008, five swimmers extended their sleep to 10 hours per day for six weeks. By the end of the study the athletes could swim faster and their reaction skills had increased. With the average Brit sleeping for seven hours every night, maybe a few more hours could make us quicker and sharper.
Lack of sleep will suppress your immune system, making you vulnerable to infection. In 2009, a study found that sleeping for less than seven hours at night increased your chances of catching a cold. Carnegie Mellon University researchers discovered that the risk increased three times compared to those sleeping for 8 hours or more every night.
Enhance your memory
While we are sleeping, our brain processes vital memory information. A study published in the journal, Sleep, found that people who slept less than six hours at night for two weeks scored less on memory tests then those sleeping for eight hours.
Be better in bed
The Sleep in America poll in 2010 found that the better rested you are, the better sex you’ll have. The poll found that 20 – 30% of men and women felt their sexual relationships were affected by their tiredness.
